JOURNAL-BOX.

Specification of Letters Patent.

Patented May 7, 1907.

Application filed June 13, 1906. Serial No. 321.488.

T all whom it Trb/,ty concern:

Be it known that I, "WILLIAM IN. NEIGH- BOUR, a citizen of the United States, residing at Denison, in the county of Grayson and State of Texas, have invented new and useful Improvements in Journal-Boxes, of which the following is a specification.

This invention relates to journal boxes, and has for its objects to produce a comparatively simple, inexpensive device of this character wherein the wheel axle or journal will be sustained for free rotation, and one in which the friction will be minimized with a consequent reduction in the liability of what are known as hot boxes being produced.

Vith these and other objects in view, the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings: Figure 1 is a central, vertical section taken on a line longitudinally of the axle or journal, through a journal box embodjdng the invention. Fig. 2 is a vertical, transverse section taken on the line a--a of Fig. 1`

Referring to the drawings, 1 designates a wheel having an axle or journal 2 provided with an enlarged substantially spherical head 3 and arranged for rotation in a box 4 having a removable cover 5 and sustained as usual in a truck frame comprising arch bars 6 and a tie bar 7.

The box 4, which is composed of the usual or any appropriate material, is of hollow formation presenting a chamber S adapted to receive the head 3 and having a journal opening 9 designed to accommodate the journal 2, there being disposed between the wheel 1 and adjacent wall of the box a series of antifriction balls 10 arranged in a suitable groove or raeeway 11 formed in the box around the opening 9, while applied in the chamber 8 above the journal is a rotary cap plate 12 provided in its lower face with an annular groove or depression 13 formed for the reception of the spherical head 3 and having on its upper face a depression 14 adapted to accommodate a series of antifriction balls 15 arranged in a groove or raceway 16 formed in the upper wall of the box.

In practice, as the ournal 2 revolves with the wheel the cap plate 12 will, owing to the action of the head 3 thereon rotate within the box, free rotation of the plate being permitted owing to the provision of the antifriction balls 15, it being apparent that under this arrangement and owing to the provision of the spherical head 3 and the rotary cap plate friction on the journal will be minimized, thus eectually obviating the creation of hot boxes and insuring a smooth free rotation of the journal Within the box.

From the foregoing it is apparent that I produce a comparatively simple, inexpensive device admirably adapted for the attain-v ment of the ends in view, it being understood that in attaining these ends minor changes in the details herein set forth may be resorted to without departing from the spirit of the invention.

Having thus described my invention, what I claim is:

1. The combination with a wheel journal having a rounded head, of a box adapted to lreceive the journal for rotation, a cap plate arranged loosely and for rotation in the box at one side of the journal and having a depression in which the rounded head travels, and antifriction devices arranged between the cap plate and adjacent wall of the box.

2. The combination with a wheel journal having a rounded head, of a box adapted to receive the journal for rotation, a rotary bearing plate arranged loosely in the box at one side of the journal and having a depression in which the head travels, antifriction devices arranged between the bearing plate and adjacent wall of the box, and antifriction devices disposed between the wheel hub and box around the journal. l

In testimony whereof, I aifix my signature in presence of two witnesses.
